Column 1	Column 2
Stones and sand	Liquid - gas (heterogenous) mixture
Salt in water	Liquid - liquid (heterogeneous) mixture
Water in flour	Solid - liquid (homogeneous) mixture
Vinegar in water	Gas - liquid (homogeneous) mixture
Fog	Solid - solid (heterogeneous) mixture
Aerated drink	Liquid - solid (heterogeneous) mixture

Answer 1

(A) Stones and sand - (V) Solid - solid (heterogeneous) mixture

• Stone is solid and sand is also solid so that the mixture is a Solid - solid (heterogeneous) mixture.

(B) Salt in water - (III) Solid - liquid (homogeneous) mixture

• Salt is solid but water is liquid and after mixing both of makes them salt dissolves in it and makes a homogeneous mixture.

(C) Water in flour - (VI) Liquid - solid (heterogeneous) mixture

• Water is liquid and Flour is solid but after mixing them they make heterogeneous mixture.

(D) Vinegar in water - (II) Liquid - liquid (heterogeneous) mixture

• Vinegar is liquid and water is also liquid but after mixing they make a heterogeneous mixture.

(E) Fog - (I) Liquid - gas (heterogeneous) mixture

• Fog is a colloid since it is a heterogeneous mixture of water, air and suspension particles.

(F) Aerated drink - (IV) Gas - liquid (homogeneous) mixture

• Aerated drink contains gas dissolved in liquid as result gas liquid homogenous mixture.
